“And, as you have just said, she has a bear of a husband, a good deal older than herself, who does not in the least care for such functions as that to which the Princess was invited. Is it not quite possible that the Princess actually attended the ball, but, for reasons of her own, desired to keep the fact of her presence there a secret; and you must remember that Lord Donal Stirling had not seen the Princess for five years.” “For five years?” said the detective sharply. “How did you learn that, Miss Baxter?” “Well, you know,” murmured the girl, with a gasp, “he met her last in Washington, and the Princess has not been in America for five years; so you see--” “Oh, I was not aware that he had met her in America at all; in fact, Lord Donal said nothing much about the Princess--all his talk had reference to this lady who impersonated her.” Jennie leaned back in her chair, closed her eyes for a moment, and breathed quickly. “I am afraid,” she said at last, “that I do not remember with sufficient minuteness the details you have given me, to be able to advise. I can only suggest that Lord Donal met the Princess herself at the Duchess of Chiselhurst’s ball. The Princess, naturally, would wish to mislead him regarding her identity; and so, if he had not met her for some time--say two years, or three years, or five years, or whatever the period may be--it is quite possible that the Princess has changed greatly in the interval, and perhaps she was not reluctant to carry on a flirtation with the young man--your client. Of course, she could not allow it to go further than the outside of the door of the Duke of Chiselhurst’s town house, for you must remember there was her husband in the background--a violent man, as you have said; and Lord Donal must have thoroughly angered the Princess by what you term his rudeness in tearing off her glove; and now the Princess will never admit that she was at the ball, so it seems to me that you are wasting your time in a wild goose chase. Why, it is absurd to think, if there had been a real disappearing woman, that you, with all your experience and all your facilities, should not have unearthed her long ago. You said at the beginning that nothing was more difficult than to disappear. Very well, then--why have you been baffled? Simply because the Princess herself attended the ball, and there has been no disappearing lady at all.” The detective, with great vehemence, brought down his fist on the table. “By Jove!” he cried, “I believe you are right. I have been completely blinded, the more so that I have the clue to the mystery right here under my own eyes.” He fumbled for a moment and brought forth a letter from his pile of documents.
